Question 73139
(a) x+1/2=x+2/3
Subtract x from both sides to get:
1/2 = 2/3
Therefore no solution
----------------
(b) (2x+3)/x=2/3
Cross multiply:
6x+9 = 3x-6
3x=-15
x=-5
-------------
(c) 3/x=2/(1-x)
Cross multiply
3-3x=2x
3=5x
x=3/5
---------
(d) (2-x)/3=(2x-1)/5
Cross multiply
10-5x=10x-3
15x=13
x=13/15
----------
etc.
The remaining problems are worked similarly.

(e) (2x-3)/4=2/3x
(f) (x-1)/2=(2-x)/3
(g) (1-k)/3=(k+2)/2
(h) (2a-3)/4=(3-a)/3
(i) 3/4=t/(t+2)
(j) 3/4=t/(t+2)
